5 such a path that there will be no necessity of advancing and receding the center of oscillation of the web pressing means; to provide mechanism for handling a plurality of rolls in a small amount of floor space and to provide mechanism which will move the rolls in such a path that they can be broughtv readily to any desired point, it having been necessary heretofore to move the rolls in a circle.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which y Fig. 1 is an end view of a roll supporting and handling mechanism constructed in accordance with this invention, and

Fig. 2 is a front elevation.

Heretofore it has been necessary to mount one or more web rolls on a rotatingreel or else on an oscillating support and thus confine the path of the web rolls to a circle or an arc of a circle and also take up a great deal of room. These rolls have to be moved to a position in which the paste can be applied. Then the web is forced against the roll. It has been necessary heretofore to rotate the reel or swing it by power along an are up to a point adjacent to that at which the paster is to be made and then it has been necessary to move the web pressing means about its center a little forward or a .little back in Order to make the paster. As stated, the principal Object of this invention is to provide an advancing means which will not necessitate the web pressing means being adjusted in this manner. It has been necessary also to move the web pasting mechanism back out of the way of the circularly advancing web roll at exactly the right time on account ofthe arcuate path of the web roll. According to this invention the path of the web roll during and directly after pasting is straight.

In the forni shown two shafts I and 2 are rotatably mounted at one end on a pedestal 3 and at the other end on a pedestal 4. The pedestal 3 is fixed in position but the pedestal 4 is connected by a tongue and groove sliding arrangement O to a base plate 5. This permits this pedestal 4 to move sideways and give side adjustment for the side register of the web of paper going to the printing press. This is accomplished by the use of a motor 9 secured on the base plate Ii,` On the shaft of the motor is a worm 8 meshing with a worm wheel 1 which carries on its shaft a screw 6 in threaded en-` gagement with the pedestal 4. In this way, as

stated, the side register can be accomplished.

These pedestals constitute the frame forv supporting the device.

The roll spindle I4 is carried in a pair of` bearing boxes Ii) which are made of two parts. The inner lpart constitutes a special link of a sprocket chain II. Of course, one sprocket chain is used on each side of the machine. These sprocket chains are carried over sprockets I2 and I3 secured to the shafts I and2 respectively said sprockets I2 being shown as larger in diameterY than the sprockets I3. The bearing boxes I0 are furnished with an keyebolt and hand wheel arrangement 3l to keep them closed except when loading or unloading; The roll spindle I4 is supplied with cone collars I5` at its ends between Which is mounted the paper web roll I6. Y

The shafts I and 2 are fixed by members I9 and 20 with respect to the movable pedestals so that they will move with it while these shafts have'slidable bearings in the fixed pedestal so that as the moving pedestal is moved back and forth the shafts merely project more `or less through the bearings on the iixed pedestal and the side register is altered. The `worm wheel I9 `and' the collar 20' secured respectively to the shafts 2 and I ensure endwise movement of the mechanism When adjustment is made for side register.

The chains are operated by a motor I1 mounted on the pedestal 4 which through a wormV I8 on its shaft operates a worm wheel I9 secured to the shaft 2. Of course, it will be understood that there are fourr or any desired number of these special links carrying the bearings I0 on each of the sprocket chains. The path of travel of these roll spindles I4 is not circular but of such` a form that four bearings can be used for two fresh rolls vand a running roll, and the other for taking on another roll. This structure takes up much less space than three rolls would on a cylindrical reel. The rolls travel in straight lines between the sprockets. This is especially important on the upper side where the path of travel makes a slight angle with the path of the web. In other words, the total space employed for the travel of one roll around the device is materially less than has been the case heretofore and much floor space is saved.

The invention is illustrated with an ordinary caterpillar tractor and belt 28 for speedlngup the new roll and enough of the pasting mechanism is shown to illustrate how, when the new roll is brought to apredetermined distance from the brush 2l, a Lsolenoid 22 is energized, either by automatic means or by pressing aV hand button, to lift alatch 23. This latch is normally in the path of a toe 24.but when lifted out of thispath a spring 25 operates through a rod 26 and arm 21 to push the brush 2| on its pivot toward the 'Y new web roll. Thus it forces the traveling web W against the `new roll I6 Ato make 'a splice. This mechanism can be mounted on a stationary frame `2.9, instead of a movable one as heretofore.'

After performing its function the `brush is reset; that is, the latch 23 and the toe'24 are interengaged and the new vrunning roll is brought down against the Vtension belts `33.4V

ltension belts and therunning web so the new roll can clearthe brush mechanism easily and permit refined adjustment of the tension. rThe Vwhole brush mechanism does, not have `to be drawn gack to allow the new roll to pass.

Although I have villustrated and described only one Vformrof theinvention `I'amaware of the fact that modifications can be made therein by any person skilled in the art without depart;

ing from the scope of the invention as expressed intheV claims. Therefore I do not wish to be Ylimited inv this respect but what I do claim isz- 1.

said device being movable to carry the fresh roll to the expiring roll position along a path wherein the surface of the fresh roll Ywill not cut across the path of the web pressing means or its frame.
